The structure of ring resonator such as split ring resonator (SRR) as well as its complementary could sometimes implemented for fulfilling specification of EM wave absorber requirement. In this paper, the experimental characterization of SRR-based multilayer X-band wave absorber is presented. The working frequency of wave absorber is focused on 9.5 GHz intended for X-band radar application. The proposed X-band wave absorber which is developed on multilayer of 1.6mm thick FR4 epoxy dielectric substrates is designed using a unit cell composed of SRR and thin strip with the dimension of 3.5mm × 3.5 mm. Some attempts to enhance the characteristics of X-band wave absorber are carried out by inserting an air gap between the SRR structure on the top of first layer and the thin strip on the top of third layer. The characterization result shows that realized X-band wave absorber could achieve the reflection coefficient value up to -42.5dB which is similar to the performance of commercialized absorbent material with the reflection coefficient of -42.9 dB.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Absorbent materials,Dielectric substrates,Electromagnetics,EM wave absorber,Experimental characterization,Ring resonator,Split-ring resonators (SRR),Working frequency[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This work is partially supported by the Indonesia Endowment Fund for Education (Lembaga Pen-gelola Dana Pendidikan, LPDP-BUDI DN), the Ministry of Finance, The Republic of Indonesia.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/PIERS-Fall48861.2019.9021606[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
